Abstract

Stator für einen Elektromotor mit einem Statorkern, der eine Anzahl Statorzähne und zwischen den Statorzähnen liegende Statomuten aufweist, wobei die Statomuten zum Aufnehmen von Statorwicklungen ausgebildet sind, wobei die Statomuten mit unterschiedlichen Tiefen ausgebildet sind, um die Anteile der Statorwicklungen einer Phase bzw. mehrerer Phasen des Elektromotors aufzunehmen.

Figure imgaf001
A stator for an electric motor comprising a stator core having a plurality of stator teeth and stator teeth located between the stator teeth, the stator slots configured to receive stator windings, the stator slots having different depths to reduce the proportions of the stator windings of one or more phases of the electric motor.
